Ensure there are no URL references used in base64 encoded value of AWS Launch Configuration

Using base64 encoded absolute URLs as part of config is not a good security practice.

For more information on how to setup launch configurations, see the AWS documentation.

In Terraform -

1. In the aws_launch_configuration resource, remove any user_data_base64 data that might contain URLs.
2. This will destroy existing launch configurations for autoscaling groups and deploy a new configuration. For more information, see the Terraform documentation.
